In accordance with the invention, im proved means are provided wherebyso-called horizontal stripes of any desired width may be knittedandparticularly whereby such stripes maybe knitted upon so-calledseamless or circular knit hosiery. Sa d so-called horizontal stripesextend circumferentially about the stocking and may vary in width fromone course to any desired multiple thereof.

While the invention is not limited inits use to any particular type ofrotary knitting machine, it is peculiarly adapted for use upon theso-called Banner knitting machine, one

i invention thereto, the attachment is illustrated as applied to aBanner machine, and is so described.

It is unnecessary to describe'at length the a said Banner machine. Inthis typeof machine the needle cylinder rotates While the cams remainstationary, and, although .the

machine is for the purpose of producing hosiery, it is obviously notlimited to this class of work.

Generally speaking the machine includes a rotating needle cylinder Imounted upon a suitable table 2 constituting a part of the frame of theknitting machine and, as is customary in this type of machine, saidcylinder is arranged to be rotated to form the leg and foot and to bereciprocated to form the heel and toe of the stocking.

ciprocating movements are substantially the same. as those shown anddescribed in the said Hemphill patent and, being well known, requireno'further description.

The means for effecting the rotary and re-' A plurality of yarn feedingelements are provided at the usual position characteristic of the Bannermachine, and a series of said elements is indicated at 3'in Fig. 4.Desirably as many as four or five yarn guidesmay be mounted side by sideat the same place,

- each to introduce its yarn or thread ascalled' for by the controllingcams, as, for example,

for the leg, the heel and toe, and the foot, etc.

All said yarn guides are pivoted uponthe latch ring 4, itself suitablypivoted'so that it may be swung up out of action to afford access to theneedlesor for any other purpose. Since the particular type of machinehere shown is the latch needle type, the member 4 is represented as alatch ring, but if the machine be equipped with spring beard needles,asmay be done within the scope of the invention, then the member 4 is inthe form of a partial ring, as well understood in this art. As many asdesired of the said yarn guides or yarn fingers may be controlled by thestriping attachment which is the subject of this invention. For thepurpose of this disclosure, but three of the yarn guides are representedas controlled by said striping attachment, but it is clearly to beunderstood that any greater or any less number may be so controlled.

Each of the said yarn guides or fingers is normally pressed or urged outof action in the general manner disclosed in the said Heinphill patent,as by a series of levers suit ably. mounted upon a standard rising fromioo front of the machine as indicated at 6 in Fig.

1. The said levers respectively ride upon suitable cams indicated at 7upon a drum 8 upon the cam shaft 9 in a manner not necessary herein todescribe, as it is desirably similar to the construction shown in thesaid Hemphill patent. Assuming that there'are I stitch variations.

.tachments of this invention is not restricted in its'application to aplain machine.

five levers in the said group, as here shown, it is evident that,according to the dictates of the cam 7 upon the disk or drum 8, thevsaid yarn guides or fingers are permitted to act in suitable order, as,for example, to supply a yarn or thread for the leg of the stocking,another for the heel, another for the foot, etc., and for splicing.

Each of the said yarn guides supplies its yarn or thread in proximity tothe knitting point, and each yarn so taken is desirably knitted upon allthe needles in action, though obviously the machine to which thisinvention is to be applied may be one where there are In other words,the at- .The machine is provided with the usual driving shaft 10having-the customary pulleys 1.1, and in the rear thereof with a shaft12 driven from the shaft 10 and having fast thereon the large gear 13known as the 104 gear. Controlled from the shaft 12 is the usualquadrant 1-1 pivoted at 15 and operated in a manner not herein necessaryto describe in effecting the reciprocation of the needle cylinder informing the heel and toe. These parts, being desirably of customaryconstruction, here need not further description.

The machine is provided with the usual narrowing pickers mounted ascustomary upon blocks indicated generally at 16, 16 in Fig. 3 and withthe customary widening pick ers mounted upon the bracket 17 shown inFig. 2.

Having thus referred to the main parts of the usual mechanism of theplain or rotary Banner machine, it is pointed out: that the presentinvention, shown for convenience as applied to such type of machine, isconcerned particularly with the formationof circumferentially extendingor so called horizontal stripes in the hose or stocking, that being thetype of fabric to which the invention is peculiarly applicable, but towhich the use of the invention is not restricted.

The said machine is provided with the usual main pattern chain 18suitably car- I!((l upon the main cam shaft 9 and driven which will nowbe described.

the Banner machine of the series of cams 7 which are removably mountedupon the pat tern drum 8 and act upon the levers 6. F or the purpose ofthe present invention the said levers 6, or certain of them, control thecorresponding yarn guide or guides during the knitting of the heel andthe toe, but for making a horizontally or circumferentially stripedstocking, such portions of the cams 7 as would control the levers 6during the formation of the leg and the foot are removed from the drum8, and the yarn guides are controlled from the attachment to which theinvention more particularly relates,

The front or main pattern chain 18 functions as usual and is alsoemployed to start the striping or rather, to release the mechanism whichgoverns or controls the striping, but the striping is stopped orterminated by the auxiliary mechanism or attachment herein disclosed,which acts to govern or control the striping. In this manner, a widerrange is given than customary to the extent of the striping,particularly with reference to the narrowness or width thereof.

Furthermore by a small compact mechanism we obtain a\more varied patternthan heretofore, and may make a stripe which is a single course in widthor which may be of any greater number of courses, as will be clear tothose skilled in the art.

In the disclosed embodiment of the invention, there is provided at theback of the machine a shaft carrying thereon the following-parts,namely: an auxiliary drum having cams controlling levers whichindividually control the several yarn guides; a

the said ratchet is actuated is released for- I action ashereinafterdescribed by the main pattern chain, and according to thearrangement of links upon the main pattern chain I and the auxiliarypattern chain, the striping is started and stopped. The said pawl is,

however, itself actuated from the IOeFgear. Referring more particularlyto the mechanism h rein shown, the 104 gear 13 rex ceives thereon anearly annular plate 18 as shown most clearly in Fig. 2. Said plate 18'has a gap 19 permitting the plate to be slipped into place by an upwardsliding movement, and when in position itis' secured flatwise against aface of the 104'gear, and is capable of being circumferentlally adjustedby reason of the curved slots 20-20 receiving the screws or bolts 21, 21from the 104 gear. Upon the said late 18 are provided a suitable number0 pins or rolls 22, here shown as two in number. If desired, fourequally.

l but two pins 22 are'employed, it is evident that for a singlerevolution of'the 104 gear, two impulses will be imparted to the partactuated thereby, if said part be in position to be so actuated. From asuitable part o f the frame and desirably from the under s1de of the bedplate 2', there. is pivotally sup- 1 ported a depending rod or actuator23. For this purpose, there is provided a bracket 24 to which the saidrod or actuator'is hinged ivoted at 25. g

ecured to or forming a part of said rod or actuator, there is provided acam 26 which is shaped as shown most clearly in Fig. 2. Viewing saidfigure, the rotation of the 104 gear is in a clockwise direction, sothat each pin 22 in turn engages the edge of the cam 26, and therebyswings the pivoted rod or actuator 23. The shape of the cam 26 beginningat its lower end is such that when 4 a pin22 engages the same, the saidrod 23 begins to move slowly from the left viewing Fig. 2, and then togain speed very rapidly up to about the middle of the cam and from thereupward the speed tapers ofi gradually to nothing. Theupper portion ofthe cam, as indicated at 27, is curved 'or inclined toward the rightviewing Fig. 2, so as to control the return swinging movement of the rod23. This prevents said rodfrom returning to the right with a jar andinsures an even or smooth return movement. -Des'irably there is alsoprovided a strip or member 28 horizontally extending from the large ormain bracket 29, and having a right angled or bent end 30 which acts asa stop to prevent the pivoted rod 23 from swingin' too far towardtheright viewing Fig. 2. gaid strip 28 is provided with a longitudinalslot 31 and is held in place by a bolt or rod 32 in a l ngthwise slot 33in the bracket 29. The eturn movement of the pivoted rod 23 is producedby the'coiled spring 33' secured thereto and to a suitable part of theframing.

At its lower end the pivoted rod or actuator 23, asshown most clearly inFig. 6, is provided with a pawl 34 pivoted thereto at 35 and adapted toengage with the teeth 36 of a ratchet 37 fast upon the'shaft 38; Thesaid shaft is suitably supported herein, by means of a bracket 39 (Fig.2) having a web or part which is secured flatwise against the main orlarge bracket 29. Upwardly extendingfrom the body portion of the bracket39 .are members 40, 41 having bearings wherein the said shaft 38 isreceived for rotation.

Preferably a brake 41a (see Fig. 4) is adapted to bear at all times upona face of the ratchet 37, it being pivoted at 41?) upon a bracket onthefframing and spring pressed against said face of the ratchet.

The said shaft 38 has also fast thereon a disk like drum 42 which isprovided with a number of circumferentially extending cams indicated at43 and which in number corre-' spond to the number of yarn guides orfingers that are to be controlled for striping. Any I drum 42. When oneof the levers 44 rests upon a cam "portion 42 the yarn-guide or fingerpertaining thereto is out of action, but when a lever '44 rests in aspace circumferentiallybetween blocks 43 of any one cam'path or track,that is, when it rests upon.the surface of the drum 42,the yarn guide orfinger pertaining thereto is in action, and striping isefi'ected bymeans of the yarn or thread so supplied.

Also fast upon the shaft 38 is a disk 46 having suitable cam portions 47secured thereon to ride under and actuate a lever 48 which is pivoted at49, as most clearly shown in Fig. 2, and at 50 is-suitably connected tothe rod or link 51 which is actuated in usual manner as'by the lever 52from a cam .upon

the pattern drum and extends upward tothc binder mechanism 53 which isnot here shown in detail, but which is or may be of the usual type uponthe Banner machine. The-construction and operation are such thatwhenevera yarn or thread that has been employed in striping is beizngchanged, the binder is opened to receive the withdrawn yarn or threadand instantly closes to hold the same.

Fast upon the left hand end of the shaft 38,

pivoted at 58 upon the large bracket 29, as

most clearly shown in Fig. 3.

The said lugs 56 traveling, as they do, 1n a "clockwise directionviewing Figs. 3and 6,

pass under the downwardly extending end or tooth 59 upon a lever 60pivotedat 61 upon the framing and provided with a coiled spring 62connected thereto at 63 and also connected at 64 to a part'to behereinafter referred to. The said coiled spring 62 tends to hold thetooth or end 59 of the lever 60 down in position to be engaged by a lug56 pending rod or actuator 23 forward (that of the chain and to beelevated thereby.

The under edge of the lever is provided with a cutout portion providinga tooth or projection 66 with a shoulder 67. The lever 60.constitutes acatch or latch, the shoulder 67 being the part thereof functioning as acatch or latch, and the lugs 56 upon the auxiliary pattern chain 55 actin turn to elevate the lever 60, thus withdrawing the catch orlatch-shoulder 67 from its functioning position so as to release a partnow to be described.

In order to hold the lower end of the deis, to the right viewing Figs. 3and 6% so that 1 will not be engaged and actuated by a pin or roll 22 onthe plate 18 (which would result in terminating the striping by the thenactive yarn guide or pin), there is provided apawl stop 68, shown mostclearly in Figs.

3 and 6. Said p a wl stop 68in its holdingor restraining positionpresents its inner edge 69 close against the rear edge of the dependingrod or actuator 23, when the latter has moved forward to turn theratclfe t controlled thereby one tooth.

It will be evident that if the depending rod 23 were free to be pulledto the left by the coil spring 33, said depending rod would be movedagain to the right by the next pin or roll 22 on the plate 18, and thestriping by the then active finger would terminate. Means ar thereforeemployed to prevent said depending rod 23 from returning to a positionwhere it can be engaged and actuated by a pin or roll 22 until it isdesired to change the striping, and this change in or terminating of thestriping is under the control of the lugs 56 upon the sprocket chain 55.

The said pawl stop 68'is pulled back by a series of levers now to bedescribed, thereby to release the parts to permit the striping to Thesaid pawl stop 68 is carried by a lever arm 70 pivotallv but looselymounted upon the shaft 38. ivotally connected to said member or finger81, shown most clearly in Figs. 1a and 3, and which is pivoted at 82upon the framing. The said member or finger 81 has formed therewith orsecured thereto a tooth 83 having a sharp edge 84 adapted to ride over(but not to rest upon a lug 85 upon the main pattern chain 18, which lug85 is also provided with :a sharp edge.

From the fact that the front member or finger 81 with its tooth 83 doesnot at any time rest upon the top of a lug of the pattern chain 18, itfollows that the pawl stop 68, 69 may be released on any forwardmovement of the striper mechanism, and there is thus no necessity for aprolonged wait, such, for example, as for four movements thereof. Thepurpose of providing the connection from the pawl stop 68, 69 to thefront chain 18 is to provide means to pull back or withdraw the pawlstop 68, 69 into a position wheie it can again be engaged by theshoulder 67 of the latch or catch, so as again to allow the striper tooperate. In other words, when the pawl stop 68, 69 is engaged by theshoulder 67, it is then held so far to the left viewing F igs.,3 and 6,that it cannot restrain the depending rod or actuator 23 from beingmoved to the left by the coil spring 33', which therefore brin s saiddepending rod 23 into a position w ere it may be struck by the nextpinor roll 22 upon the plate 18, and thereby be caused to turn the ratchet37 one tooth.

The said pawl stop 68, 69, as shown most clearly in F ig. 4, is of ageneral right angular form, and in the construction shown the pawl stops68, 69, which is secured to the u per end of the lever 70, directlyengages t e back face of the said depending rod 23, thereby at theproper time holding the pawl 34 thereon forward or to the right viewingFigs.

3 and 6, thus, as stated, preventing said pawl stop 68, 69, the pawlwithits depending rod 23 may be moved inwardby the coil spring 33', andthe next pin or roll 22 upon the plate 18 will act upon the cam 26 onsaid depending rod 23, and thereby actuate said depending rod and pawlto impart. another stepped and therefore the striping vmovement to theratchet 37 which results in a change in the horizontal striping, whichchange, therefore, is governed or controlled never rests upon the top ofa lug 85 (but on the contrary the tooth 85 rides Without pause up, overand down the lug 85), the result is to bring the pawl stop 68, 69 backor inward,

viewing Figs. 3 and 6, so that said pawl stop 68, 69, is therebypositioned back of and is held by the shoulder 67 on the catch or latch60, and said pawl stop 68, 69 will stay in this position unless anduntil said catch or latch is again lifted by a projection 56 on a lug ofthe rear sprocket chain 55, in which event the horizontal striping isterminated.

The construction, particularly if there be four pins on the 104 gear, asalready referred to, is such that a stripe may consist of a singlecourse or of two, three or more courses. A movement of the ratchet 37 tothe extent of two teeth is necessary to make a single course, namely, amovement one tooth to throw in the desired yarn and a movement ofanother tooth to throw it out. A single movement of the pawl 34 movesthe auxiliary chain 55 two links. Inasmuch as by the describedconstruction a tooth may be moved at longer or horterintervals asdesired, it is ewident thad each stripe may be of any desired width.Each series of stripingsis initiated from the front or main chain whichthrough the described connections 72, 76,? 9, 81, etc. pulls A back thepawl stop 68, 69, this action releasing the striping mechanism. A lug 56upon the auxiliary pattern chain terminates the striping. I

The main or body yarn of the stocking or other fabric is, of course,replaced by a striping yarn when striping is to be effected, the

. striping yarnbeingv therefore a substitute and not a reinforcing yarn.When striping is to begin, a lug 85 upon the front or main chain liftsthe special member orifinger 81 and immediately lets it again fall, butthe lifting movement acts to pull inward or rearward the pawl stop 68,69,'as already described, thus starting the color striping by releasingthe mechanism which governsor controls the same. The pawl stop 68, 69

. having been pulled back or inward, the depending rod 23 with its pawl34 can be operated by the next roll or pin 22 to turn the shaft 38, andthe parts mounted thereon which. therefore function as already describedto make whatever stripes 'are indicated and provided for by thearrangement of pins on the pattern drum 42 (Fig. 4). This stripingcontinues until the next lug 56 on the chain 55 comes into action andlifts the said latch or catch 60 so as to terminate the striping,whereupon the main body yarn or some other color of yarn is instantlybrought into action as a substitute yarn, this depending upon thearrangement of the cams the pattern drum 42 is" turned step by step.

With two pins or rolls 22 upon theplate 18, the stripes would be at theminimum two courses in width, but if four equally spaced pins beemployed, each stripe might at the minimum be one course in width.

The front set ofv leaves 6 are practically non-functioning during theformation of the leg and foot, and this is etfectedfas stated, throughthe removal of'the necessary cams from the drum 8." Suflicient cams are,however, leftupon the drum 8 to control the necessary front I levers forthe heel and the toe.
